Homescreen/widgets/menu not showing

I just rooted my android (LG p500) and was removing bloatware using titanium backup. I accidentally deleted something which caused the homescreen to go black with no widgets showing, I cant even see the menu. I can still see and work with the top bar. When the phone is locked I can see the wallpaper I had but as soon as I unlock it goes black again.
Please HELP !!
